MongoDB\Driver\Manager::executeBulkWrite — Execute one or more write operations

### Beschreibung

final public MongoDB\Driver\Manager::executeBulkWrite(string `$namespace`, MongoDB\Driver\BulkWrite `$bulk`, ?array `$options` = `null`): MongoDB\Driver\WriteResult

Executes one or more write operations on the primary server.

A MongoDB\Driver\BulkWrite can be constructed with one or more write operations of varying types (e.g. updates, deletes, and inserts). The driver will attempt to send operations of the same type to the server in as few requests as possible to optimize round trips.

The default value for the `"writeConcern"` option will be inferred from an active transaction (indicated by the `"session"` option), followed by the connection URI.

### Parameter-Liste

`namespace` (string)

  A fully qualified namespace (e.g. `"databaseName.collectionName"`).

`bulk` (MongoDB\Driver\BulkWrite)

  Die auszuführenden Schreibvorgänge.

`options`

  options
  Option | Type | Description
  --- | --- | ---
  session | MongoDB\Driver\Session | Eine Session, die mit dem Vorgang verknüpft werden soll.
  writeConcern | MongoDB\Driver\WriteConcern | Eine Schreibanweisung (Write Concern), das auf den Vorgang angewendet werden soll.

### Rückgabewerte

Gibt bei Erfolg ein MongoDB\Driver\WriteResult zurück.

### Fehler/Exceptions

- Throws MongoDB\Driver\Exception\InvalidArgumentException if `bulk` does not contain any write operations.
- Throws MongoDB\Driver\Exception\InvalidArgumentException if `bulk` has already been executed. MongoDB\Driver\BulkWrite objects may not be executed multiple times.
- Wirft eine MongoDB\Driver\Exception\InvalidArgumentException, wenn die Option `"session"` in Kombination mit einer unbestätigten Schreibanweisung verwendet wird.
- Wirft eine MongoDB\Driver\Exception\InvalidArgumentException, wenn beim Analysieren von Argumenten ein Fehler auftritt.
- Wirft eine MongoDB\Driver\Exception\ConnectionException, wenn der Aufbau einer Verbindung zum Server fehlschlägt (aus einem anderen Grund als der Authentifizierung).
- Wirft eine MongoDB\Driver\Exception\AuthenticationException, wenn eine Authentifizierung erforderlich ist und fehlschlägt.
- Wirft eine MongoDB\Driver\Exception\BulkWriteException, wenn ein Schreibvorgang fehlschlägt (z. B. wegen eines Schreibfehlers oder eines Fehlers bei der Anwendung einer Schreibanweisung).
- Throws MongoDB\Driver\Exception\RuntimeException on other errors.

### Changelog

Version | Beschreibung
--- | ---
PECL mongodb 2.0.0 | The `options` parameter no longer accepts a MongoDB\Driver\WriteConcern instance.
PECL mongodb 1.21.0 | Passing a MongoDB\Driver\WriteConcern object as `options` is deprecated and will be removed in 2.0.
PECL mongodb 1.4.4 | MongoDB\Driver\Exception\InvalidArgumentException will be thrown if the `"session"` option is used in combination with an unacknowledged write concern.
PECL mongodb 1.4.0 | The third parameter is now an `options` array. For backwards compatibility, this paramater will still accept a MongoDB\Driver\WriteConcern object.
PECL mongodb 1.3.0 | MongoDB\Driver\Exception\InvalidArgumentException is now thrown if `bulk` does not contain any write operations. Previously, a MongoDB\Driver\Exception\BulkWriteException was thrown.

### Beispiele

Beispiel #1 MongoDB\Driver\Manager::executeBulkWrite() example

`<?php
$bulk = new MongoDB\Driver\BulkWrite();
$bulk->insert(['_id' => 1, 'x' => 1]);
$bulk->insert(['_id' => 2, 'x' => 2]);
$bulk->update(['x' => 2], ['$set' => ['x' => 1]], ['multi' => false, 'upsert' => false]);
$bulk->update(['x' => 3], ['$set' => ['x' => 3]], ['multi' => false, 'upsert' => true]);
$bulk->update(['_id' => 3], ['$set' => ['x' => 3]], ['multi' => false, 'upsert' => true]);
$bulk->insert(['_id' => 4, 'x' => 2]);
$bulk->delete(['x' => 1], ['limit' => 1]);
$manager = new MongoDB\Driver\Manager('mongodb://localhost:27017');
$writeConcern = new MongoDB\Driver\WriteConcern(MongoDB\Driver\WriteConcern::MAJORITY, 100);
$result = $manager->executeBulkWrite('db.collection', $bulk, ['writeConcern' => $writeConcern]);
printf("Inserted %d document(s)\n", $result->getInsertedCount());
printf("Matched %d document(s)\n", $result->getMatchedCount());
printf("Updated %d document(s)\n", $result->getModifiedCount());
printf("Upserted %d document(s)\n", $result->getUpsertedCount());
printf("Deleted %d document(s)\n", $result->getDeletedCount());
foreach ($result->getUpsertedIds() as $index => $id) {
printf('upsertedId[%d]: ', $index);
var_dump($id);
}
/* If the WriteConcern could not be fulfilled */
if ($writeConcernError = $result->getWriteConcernError()) {
printf("%s (%d): %s\n", $writeConcernError->getMessage(), $writeConcernError->getCode(), var_export($writeConcernError->getInfo(), true));
}
/* If a write could not happen at all */
foreach ($result->getWriteErrors() as $writeError) {
printf("Operation#%d: %s (%d)\n", $writeError->getIndex(), $writeError->getMessage(), $writeError->getCode());
}
?>`

Das oben gezeigte Beispiel erzeugt eine ähnliche Ausgabe wie:

    Inserted 3 document(s)
    Matched  1 document(s)
    Updated  1 document(s)
    Upserted 2 document(s)
    Deleted  1 document(s)
    upsertedId[3]: object(MongoDB\BSON\ObjectId)#5 (1) {
      ["oid"]=>
      string(24) "54d3adc3ce7a792f4d703756"
    }
    upsertedId[4]: int(3)
